What is dipotassium EDTA?

Details:

EDTA-2K, a kind of blood anticoagulant, is a kind of anticoagulant. It can inhibit platelet aggregation and make blood non coagulant. Therefore, anticoagulant, anticoagulant tube and whole blood analyzer are commonly used and widely used. The use of EDTA-2K will be described below.   The international blood Standards Committee recommends the use of EDTA-2K anticoagulant for the whole blood cell count. In vacuum blood collection, the leukocyte growth can be preserved in a short time by using the two hydrate of EDTA as anticoagulant, which can prevent platelet aggregation and preserve platelets.

In addition to being anticoagulant, EDTA-2K has many applications in industrial production, environmental optimization and other fields.

EDTA-2K can be used as a retarder for magnesium phosphate cement, a new gel material, compared with borax used in traditional magnesium phosphate cement. It has better retarding effect, can extend the setting time of magnesium phosphate repair system, ensure the strength of magnesium phosphate cement, and make it more widely used in the field of highway, bridge deck, aircraft runway and other rapid repair.

EDTA-2K is also used as stabilizer to form desulfurization synergist in oilfield production, which can not only maintain the stability of desulfurization synergist, but also chelate calcium and magnesium ions in the operation system to stabilize the water quality of the whole operation system. It can effectively react with sulfide in equipment and achieve the purpose of removing sulfide, and has good desulfurization effect and ensures the safety of oilfield construction.

EDTA-2K is also used to prepare deodorant, such as toilet deodorant, decomposition pesticide and odor molecule remover. In addition, according to the description of relevant patents, potassium EDTA can be prepared by calcining, pickling, washing and drying at high temperature successively.
